The European Spallation Source, a facility being built in Sweden, is seeing its costs and planned start date spiral out of control, according to news reports.
The ESS’s initial operations phase, which will run from 2019 to 2025, will cost at least €150 million more than the €850m previously expected, the journal Science reported on 24 July. The news website Science Business said that this was due to higher than expected prices for concrete, steel, personnel and insurance.
As a consequence of the cost overruns, the project’s management team has been forced to consider revisions to the facility’s operational schedule, the reports said. Under each of various scenarios considered by the ESS Council, the facility will run proton beams with just two megawatts of power by 2023, instead of the planned five megawatts.
